CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 362,773, dated May 10',1887.

Application filed November15, 1580. Serial No. 218,844.

To all whom it may concern:

Be it known that, 1, JOHN A. NEICHTER, a citizen of the United States,residing at Orrville, in the county of WVayne and State of Ohio, haveinvented certain new and useful Improve ments in Car-Brakes, of whichthe following is a specification.

This invention relates to an improvement in carbrakes, and has for itsobject to provide means whereby the brake-shoes when applied to thewheels may have an elastic slightly-vibratory motion, instead of a rigidor fixed bearing. This improvement permits the shoes to be applied withthe full ordinary pressure without liability of sliding or skidding thewheels.

The invention is illustrated in the accompanying drawings, in whichFigure l is a side view of part of a cartruck, showing my improvement.Fig. 2 is a view of the box. Fig. 3 is a view of the clip. Figs. 4. and5are views of the brake-shoe. Fig. 6 is a'vertical section of brake-shoeand the parts which attach it to the beam. Fig. 7 is a rear view of aear-truck, showing my inr provement. Fig. Sis a top view of the brakebeam. Fig. 9 is a cross-section of the brakebeam.

The letter A designates a ear-wheel; B, the frame of the truck; G, thebrake-beam, suspended from the frame by the usual hanger, d, and e thebrake-shoes.

The brake-shoes e are attached in some suitable way to a box, F, betweenwhich and the beam 0 is a rubber cushion, g. This rubber cushion beinginterposed between the brake shoe and brake-beam and there being norigid connection between those part-s, it will be seen an elasticattachment is provided whereby the brake-shoe will yield when pressureis applied, and also the brake-shoe, when pressed against the wheel, mayvibrate or tremble independently of the beam to such a degree as willprevent it from causing the wheel to slide on the rail.

The particular construction I employ for attaching the brake-shoes andthe rubber cushion is new and useful, and consists of a metal clip, G,having three sides to take on the brakebeam. A hole, 71, in one sidereceives a bolt,

2', which passes through the beam 0, and is (No model.)

made fast by a nut, i. The center side of the clip G is provided withone or more lugs, k, and at one corner the clip is hollowed out, as atd, to receive the hanger d. cushion g fits around the three sides of theclip, and is preferably molded to give it the desired shape. It has ahole in its center side for the passage of each lug k on the clip. Thebox F has three sides, corresponding to the sides of the clip G, and thedimensions of these sides adapt the box to take over and fit closearound the said ru'bber cushion g. This box has slots Z in its centerside-one slot for each lug k on the clip-and is provided with flanges m,which inclose the rubber cushion g and partly inclose the clip G. Aspace, a, (see Fig. 7,) is left at each side between the rubber cushionand box-flange m. This space allows the rubber to be compressed, andthereby afford motion to the box. The box F is secured to its positionon the rubber cushion and clip by suitable pins or keys, 0, which arepassed through the lugs k, as seen in Fig. 6.

The brakeshoes c are here shown attached to the box F by aknuckle-joint. Each shoe has at its back a knuckle, p, which has avertical slot, p, and each box F has at its cen ter side a socket, q,which the shoe-knuckle occupies. This manner of attaching the shoes,separately considered, is not my invention; but this knuckle-jointco-ope ates with the box and rubber cushion in permitting the desiredelastic vibratory motion to the shoe, and I therefore claim thecombination. A pin, 0, passes down through the socket q and slot 1),and, while confining the shoe to its position, allows it to tilt orvibrate. A. boss, 8, is on The rubber the box F above and below thesocket, and

serves as a stop for the shoe to tilt against.

In order to obviate the effects on the brakeshoes resulting from a rigidconnection between the brake-rod t and brake-beam O, I provide a rubberspool, a, which is slipped on the rod t and rests against the beam. Awasher, o, is against the rubber spool, and a nut, to, on the rod isagainst the washer. This rubber spool a affords, when the brakes are on,a desirable degree of elasticity to the beam and greatly favors thevibratory motion of the shoes before referred to.

The advantages of the parts and combinabrakes may be applied with themaximum ordinary pressure without liability of sliding the wheels, andthe jar and strain on the car-body incident to applying the brakes asordinarily rigged is almost entirely obviated.

Having described my invention, I claim and desire to secure by LettersPatent of the United States 1. In a car-brake, the combination of thebrake-beam, a clip attached to the beam and provided on its center sidewith lugs k, a box, F, having three sides and flanges, m, and providedon its center side with slots Z for said clip-lugs, a rubber cushion, g,between the said clip and box, suitable keys, 0, through the said lugsto confine the box, and a brake-shoe attached to the box, for thepurpose set forth.

2. Ina car-brake, the combination of abrakebeam, a clip attached to saidbeam, a box having three sides and movably attached to said clip, arubber cushion interposed between the inside of said'box and the outsideof said clip,

and a brake-shoe attached to said box, for the purpose set forth.

3. Inacar-brake, the combination of abrakebeam, a clip, G, attached tosaid beam, a box having three sides and inclosing said clip, a rubbercushion interposed between said clip and said box, the latter having onits center side a socket, and a brake-shoe having a knuckle which fitsin said socket, substantially as and for the purpose set forth.

4. In a car-brake, the combination, with a brake-beam, of a clip, G,being hollowed out at one corner, the hanger d, which passes throughsaid opening, the rubber cushion g, the in- 'closingbox F, andbrake-shoe 6, attached to said box, substantially as set forth. a

In testimony whereof I affix my signature in the presence of twowitnesses.
